I recently uploaded http://www.scp-wiki.net/scp-3701. I'd spent a few weeks making it before I joined the Foundation, however, just 15 minutes or so after upload, it's got a rating of -3! While it might be early to tell if there is an issue, this does seem to be a starting trend. I talked about it with a few friends who are also fairly new to the Foundation. I'd love to hear critique on it, I'd hate to have it taken down before I can fix whatever issues it has!

This forum is for drafts, not posted SCPs. Posting an SCP implies you already had the draft looked at. In the future, you should use a sandbox to draft your SCP, then share it here.

(As this has been moved, the above forum refers to the Draft and Critique forum)

As for why your article isn't doing too well, there are two reasons:
The first is that it isn't very interesting. Its a succulent that causes people to see the room differently. There is no emotion or story here. There is no reason for the reader to look at this and say that they were able to pull something positive from it. As it stands now, its just an anomalous succulent. Nothing more.

The second reason is because despite your effort at using clinical tone, you only ended up making the article as a whole very confusing to read.

herein it begins to alter the room around it to the perception of a viewer.

This line implies that the room itself changes based on what the viewer thinks it should look like (their perception). You contradict yourself by saying that the room is perceived differently by different people. Those are two different things. As a result, its difficult to tell what the actual anomalous property is.
